A Store is one RDF dataset instance - it is the unit of query. The Store class is the SDB specific mechanisms need to implement an RDF Dataset. DatasetStore provide the dataset interface. A store consists of a number of handlers for different aspects of the process of setting up and querying a database-backed Store. This means Store for new databases can be assmelbed from those standard components that work, with database-specific code only where necessary. A common case if the formatting of the database - this is often DB-specific yet SQL generation of query is more standard.
